Requirements and availability of sand for the protection of Nechochea and Lobería beaches

The coast of Lobería and Necochea is characterized by cliffsand narrow beaches. The inlet of the Quequén Grande river used to alter the coastline. The construction of jetties related to the Quequén Harbour induced huge accumulations of sand towards Necochea, and a critic erosive process of cliff and...

description The coast of Lobería and Necochea is characterized by cliffsand narrow beaches. The inlet of the Quequén Grande river used to alter the coastline. The construction of jetties related to the Quequén Harbour induced huge accumulations of sand towards Necochea, and a critic erosive process of cliff and beach to the east. Beach width reduces from 300 m at the west to 40-60 m to the east. Considering regional sand scarcity, the eastern beaches are characterized by more sand variability. Greater variations in the sand balance were assigned to human activity. Waves coming from the E, SE and S deliver more energy along this eastern sector. On the other hand, submerged zones of these beaches have less availability of sand. Greater availability of fine sand was recognized towards Necochea. The Quequén Grande river has much effect on the estuarine dynamics during ENSO-triggered floods, although sedimentation is dominated by silt supply.
